The least common denominator is 5y, and can be obtained by multiplying
-1/y by 5/5 to get -5/5y.
If we add the numbers using the least common denominator, we get:
-5/5y + 2/5y = -3/5y
Well first set up the first ratio as 6/24. That is commercial mins over show time mins. Then to keep the units the same convert 2 hours into minutes which would be 120 minutes. Then set up your next ratio as x/120 since you’re trying to find the commercial minutes. Then cross multiply so that it’s 24x=720 and then x=30 and that’s the amount of commercial minutes for 2 hours.
The rice will cost $17.6 for serving 40 people
<h3><u>Solution:</u></h3>
We need to determine the cost of serving 40 people with rice
Arborio rice is purchased in 2-pound boxes for $1.99
The price of 1 pound box will be ![\frac{\$ 1.99}{2}=\$ 0.995](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%24%201.99%7D%7B2%7D%3D%5C%24%200.995)
1 Pound (lb) is equal to 16 ounces (oz)
Therefore, the price of 16 ounces is $0.995
A cup of raw Arborio rice weighs 7 ounces and it serve 1 people
![\begin{array}{l}{\text { The cost per person is } \frac{\$ 0.995}{16} \times 7=\$ 0.44} \\\\ {\text { The cost for serving } 40 \text { people }=\$ 0.44 \times 40=\$ 17.6}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%5Ctext%20%7B%20The%20cost%20per%20person%20is%20%7D%20%5Cfrac%7B%5C%24%200.995%7D%7B16%7D%20%5Ctimes%207%3D%5C%24%200.44%7D%20%5C%5C%5C%5C%20%7B%5Ctext%20%7B%20The%20cost%20for%20serving%20%7D%2040%20%5Ctext%20%7B%20people%20%7D%3D%5C%24%200.44%20%5Ctimes%2040%3D%5C%24%2017.6%7D%5Cend%7Barray%7D)
Therefore rice will cost $17.6 for serving 40 people
<span>Simplifying
y = 20x + 500
Reorder the terms:
y = 500 + 20x
Solving
y = 500 + 20x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 500 + 20x</span>
